The Raspberry Pi uses a variety of input/output devices based on protocols such as HDMI, USB, and Ethernet to communicate with the outside world. In this class you will learn how to use these protocols with other external devices (sensors, motors, GPS, orientation, LCD screens etc.) to get your IoT device to interact with the real world. Most physical devices use analog signals; however computer hardware is digital so in this class you will learn how these signals are converted back-and-forth and how this must be considered as you program your device. The basic design of a sensor-actuator system will also be covered. You will also learn how to build more sophisticated hardware systems using Raspberry Pi expansion boards to create fun and exciting IoT devices. Please note that this course does not include discussion forums.

Module 1

This module presents the use of the Raspberry Pi to connect to the Internet, from a user perspective. The first way to use the Raspberry Pi as a networked device is to use it as a general-purpose computer rather than as a programmed IoT device. Using networking with a Raspberry Pi in this way is similar to using the network from any Linux machine, and we present its use in this module. We also present the standard Internet protocols that must be understood in order to develop network programs.
